PHCKET-POINTING iviAoinrie.

SPECIFICATION forming part of Letters Patent No. 391,628, dated @otober 23, 1888.

(X model.)

' of New York, have invented a new and useful Improvement in Picket-Pointing Machines, of which the following is a specification.

The object of my invention is to provide a simple and effective machine whereby pickets may be accurately and uniformly pointed or headed-that is, may have their ends which are to be uppermost when set rounded off or sharpened.

My invention in its most complete form provides for operating upon two pickets at one operation, one picket being rounded off or pointed by a curved or arc-shaped cut, so as to give it a Gothic or rounded form, and the other picket having its end chamfered or given a slanting cut in a straight line, so that the end of the picket when finished will be wedgeshaped.

Theinvention consistsin novel combinations of parts, which are hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a plan .of the machine, a portion thereof, which provides for operating upon a second picket at the same operation, being broken away to reduce the size of the figure. Fig. 2 is a side elevation of the machine, a portion of the op crating-lever being broken away; and Fig. 3 is an end elevation, also showing a portion of the operating-lever broken away.

Similar letters of reference designate corresponding parts in the several figures.

A designates the stationary frame of the machine to which the operating parts are at tached.

' I will first describe the machine in so far as I it is constructed to operate upon a single picket at one operation and to give the same a Gothic or rounded point, and I will then de scribe the attachments for the machine, which provide for, at the same time operating upon, a second picket to give it a wedge-shaped point. i

B designates a bed for a picket, and A A designate two uprights, which are secured to the frame A and against which the bed B is supported. By the bed and uprights the picket is held in position, as shown by dotted lines in Fig. 2, to have its lower end pointed or rounded. Thebed B has downwardly-extending arms I) b, which are secured in place to give the bed B any desired angle of inclination by means of clamping bolts or screws 1), which pass through slots b in the arms I) b. The arm I) is secured to the upright A, and the arm I) is secured to the mainframe A. I also provide in the frame A other holes, a, in which the bolts 1) may be placed for holding the bed B in a substantially horizontal position when it is desired to cut off the end of the picket, so as to give it a truly half-round or semicircular outline.

B designates a piece which forms a stop for the lower end of the picket, and which has at its edge or top a seat or face, 12 of lead or like soft material, which will not injure the edge of a knife striking against it. This stop 13 is, as here shown,not secured directly to the bed, but is secured to an adjustable side piece or block, B which is fastened to the side of the bed B by a bolt, Zf", passing through a slot, b in said piece 15*. By loosening the bolt 1) and shifting the piece B toward or from the end of the bed 13 the stop B may be brought in proper position to hold the picket so that the knife, soon to be described, will terminate its out exactly at the middle of the width of the picket. The stop B is secured to the piece 13 by a bolt, b passing through a slot, b in the stop B, and thus provision is atforded for shifting the stop upward or downward, so as to bring the knife-seat b at a point to receive the impact of the cutting-edge of the knife when itterminates its operation.

0 designates a shaft which is supported in bearings c,and which has upon one end a lever, D, and also has a balancing-weight, O. I have not shown the full length of the lever D, but have in Fig. 2 represented it as broken away to reduce the size of the figure. The lever D is of suliicient length to form a handle whereby the lever may be easily swung upon 9 its fulcrum,which is the shaft 0, and its knife (I made to operate upon a picket on the bed B. The knife (I is not, as here represented, secured directly to the lever D,but upon a knifeblook or support, d, which is adj ustable lengthwise of the lever and toward and from the lever-fulcrum, so as to adapt the knife for operating upon pickets of different widths.

In the lever D is a slot, d and the knifeblock or support d is held in place by a clamping-bolt, d so it will be seen that it can be readily shifted upon the lever D toward and from its fulcrum, and then tightly clamped in a new position. When the picket is placed upon the bed 13, as represented by dotted lines, the knife d being adjusted at the desired distance away from the lever-fulcrum, so as to be above the upper edge of the picket, the lever D is swung downward toward the right hand of Fig. 2, and thereby the top corner of the picket is cut off on a curvature to give the end of the picket the desired shape when completed. Afterward the picket is turned over with its other edge uppermost upon the bed 13, and the other corner of the head of the picket is cutaway in a corresponding manner. The counterbalanceweight O is so secured to the shaft 0 that it serves to very nearly balance the lever D, in whatever position the lever is placed, and therefore it serves to greatly steady the operation of the lever and renders the handling of the lever less laborious.

D D designate stops which serve to limit the swinging movement of the lever. One of these stops, D, is upon the upright A", and the lever D strikes against it when swung to the position shown in Fig. 2, and the other, D is secured to the lever and strikes upon the frame A when the lever is swung downward. A piece of rubber or like cushioning material, (1*, may be inserted in the end of each stop D D and the stops may be secured in place each by a bolt, d passing through a slot, d, in the stop, thus affording ample provision for the adjustment of the stops.

I will now describe the additional features which are necessarily applied to the machine when two pickets are to be cut at one operation.

It will be observed that the plane in which the lever D swings is substantially parallel with the vertical plane in which the bed B is situated. To cut a second picket at the same operation, I provide a second bed, E. (Best shown in Fig. 3.) I secure to the side of the frame a bracket, F, which may have a flange, f, overlying the top of the frame, asshown in Fig. 3, and be secured in place by a single bolt, f, as shown in Fig. 2. Upon the bracket F is formed a dovetailed slideway, f having a downward taper, as shown in Fig. 2, and the second bed E has at the bottom a slide or shank portion, 6, which slips downward into the slideway f, and by this or any other suitable construction I provide for detachably securing the second bed E upon the machine.

The bed E comprises an angle-shaped supportingpiece, E, which has downwardly-extending arms 6, and is secured to the piece E by boltse passing through slots e in said arms. A number of holes, e, are provided in the piece E, and into any two of these holes the bolts 6" may be inserted, and the position of the angle-supporting piece E upon the part E may be shifted so as to accommodate pickets of different sizes, and so as to cut the ends of the pickets at different angles. The two pieces E E may be considered as together forming the second bed E.

Extending upward at the side of the piece E and from the bracket F or other portion of the frame is a cheek-piece or upright, G, the face of which is substantially parallel with the vertical portion of the bed E, and between which and the bed a picket rests, as shown by dotted lines in Fig. 3.

It will be observed that the second bed E is in a vertical plane, which is substantially at right angles to the plane of movement of the lever D, and I employ upon the lever D a second knife, g, which is so placed as to cut in the plane in which the lever swings.

When a picket rests upon the bed E, in the position shown by dotted lines in Fig. 3, it will be observed that one of its lower corners projects toward the right hand beyond the cheekpiece or upright G, and as the lever D is operated its knife 9, the edge of which swings in a plane about coincident with the right-hand edge of the cheek-piece G, descends upon this projecting corner and cuts it off by a straight out, so that at each operation of the lever, while the knife d cuts one picket with a curved or rounding out the knife 9 cuts the other picket with a straight out.

Although primarily intended for cutting pickets, my machine may with equal advantage be employed for cutting shingles to give them ornamental shapes.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, with a bed for a picket, of .a lever pivoted to swing in a plane substantially parallel with said bed and carrying a knife for acting upon the upper edge of the picket and rounding the upper corner of its end as the lever is swung, a second bed for a picket arranged in a plane transverse to the plane of the first bed, and a second knife upon the lever, whereby the corner of the picket on the second bed is chamfered off by the downward movement of the lever, substantially as herein described.

2. The combination, with the upright A, of the bed B, adj ustably secured to said upright, a swinging lever, a knife-support mounted upon the lever, so as to swing with the lever in a curved plane, and adjustable lengthwise of the lever toward and from the fulcrum of the lever, substantially as specified.

3. The combination, with the bed B, adjustable to different degrees of inclination, of a stop B, adjustable both lengthwise of the bed and transversely thereto, and a swinging lever carrying a knife, said knife being adjustable on the lever and adapted to contact with said stop, substantially as specified.

dovetailed slideway, the bed E, detachably fitted in said slideway, and the cheek-piece or upright G, for holding a picket placed on the bed E, and the second knife 9 upon said lever, substantially as herein described.
